Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139470, here are decompositions:

11 + 139459 = 139470
13 + 139457 = 139470
31 + 139439 = 139470
41 + 139429 = 139470
47 + 139423 = 139470
61 + 139409 = 139470
73 + 139397 = 139470
83 + 139387 = 139470

Showing the first eight; more decompositions exist.
